LIBS System Companion Guide

Laser Induced Breakdown Spectroscopy (LIBS) utilizes the interaction of high power density Laser light with matter to generate transient plasma, and uses an optical system to collect the emission spectra of atoms and ions in the plasma. Qualitative or quantitative analysis of chemical elements. Laser-induced spectroscopy (LIBS) technology has the characteristics of non-contact, less destructive, rapid in-situ remote analysis, and simultaneous online monitoring of multiple elements.
Laser-induced breakdown spectroscopy is widely used in many fields, such as on-line analysis of steel composition, coal quality analysis, space exploration, environmental and waste monitoring, cultural heritage identification, industrial process control, detection, geochemical analysis, etc.

The basic composition of LIBS system

The LIBS system is mainly composed of: Pulsed Laser, fiber Spectrometer, focusing lens, sample, turntable, coupling lens, fiber holder, fiber and other parts. Among them, the core parts are pulsed lasers and fiber spectrometers. Let me show you how to "tailor-made" lasers and spectrometers to perfectly match the LIBS system.

Choice of pulsed lasers

Laser type: Q-switched pulsed laser, ns-level pulse width, mJ-level energy, air-cooled/water-cooled optional

Typical wavelength: 1064nm, other wavelengths can be loaded: 532nm, 355nm, 266nm

High energy stability: <2%

Small pulse jitter: Jitter<1ns

External trigger control laser pulse output, Q switch and TTL synchronization signal, synchronous control with spectrometer

Select different pulse energies and repetition frequencies for substances in different (solid, liquid, gas) forms
